Wireless Sim Resource

A Sim resource represents a physical SIM that can connect to a wireless network.

To avoid ambiguity, Sim (initial cap) refers to the Sim API resource. SIM (all caps) refers to the physical Subscriber Identity Module (that is, a SIM card) associated with a Sim resource.

A Sim resource must have a Rate Plan before it can become active. The Rate Plan describes the capabilities and restrictions that apply to the SIM.

Asynchronous resources

The Sim resource operates asynchronously. To receive a notification when a Sim resource has finished updating, you should provide a callback URL and a callback method with your initial HTTP request. This is demonstrated in an example below.

Sim Properties

sid SID<DE>

The unique string that we created to identify the Sim resource.

Pattern:^DE[0-9a-fA-F]{32}$

Min length:34

Max length:34

unique_name string

An application-defined string that uniquely identifies the resource. It can be used in place of the resource's sid in the URL to address the resource.

account_sid SID<AC>

The SID of the Account to which the Sim resource belongs.

Pattern:^AC[0-9a-fA-F]{32}$

Min length:34

Max length:34

rate_plan_sid SID<WP>

The SID of the RatePlan resource to which the Sim resource is assigned.

Pattern:^WP[0-9a-fA-F]{32}$

Min length:34

Max length:34

friendly_name string

The string that you assigned to describe the Sim resource.

iccid string

Status Values

The table below describes the available status values of a SIM represented by a Sim instance.

Status

Description

new

The SIM is waiting to be activated so that it can join the network. A Sim can remain new indefinitely at no charge, but once it becomes ready or active, it cannot be returned to new.

ready

The SIM can connect to the network and is capable of consuming network resources in accordance with its Rate Plan, but no monthly fee will be charged .Once the SIM has consumed 250KB of data, or three months have passed, the SIM will transition automatically to active status. On the fifth Command sent to_sim or from_sim, the device will automatically become active.Use the ready status when shipping your device to a customer if you aren't exactly sure when they will start using it.Note This status is not available for the Narrowband developer plan.

active

The SIM can connect to the network and is capable of consuming network resources in accordance with its Rate Plan.

suspended

The SIM is blocked from connecting to the network. After three months of suspension at no charge, a suspended monthly fee will be initiated. See Suspended SIM Fees in Programmable Wireless Pricing for more details.

deactivated

The SIM is blocked from connecting to the network. After 72 hours, the SIM will transition automatically to the terminal status canceled. Use this status when you never want the SIM to reconnect — for example, if it has been lost or stolen.

canceled

Terminal status. The SIM is blocked from connecting to the network and can never be reactivated.

scheduled

The upstream network operator is temporarily unable to update the status of this SIM. Its status will be automatically updated to the requested status when the upstream network operator resumes accepting transactions.

updating

The SIM is in the process of being asynchronously updated. While the Sim is updating, it may not be possible to modify some fields. In these cases, you will receive a 409 Conflict response.

Callback values

If a callback URL is present in your request, the asynchronous request made to that URL will contain the following parameters.

Parameter

Description

SimSid

The SID of the SIM that this callback is in reference to.

SimUniqueName

The SIM's UniqueName, if it has one.

SimStatus

An updated string representing the new status of the SIM.

ErrorCode

If an error occurred, an error code is provided.

ErrorMessage

If an error occurred, an error message is provided.

ApiVersion

The version of the API that your initial request was made to.

AccountSid

The unique SID of the Account that this SIM belongs to.

If the callback method was set to POST or not provided, the callback parameters will be delivered as HTML form parameters. If the callback method was set to GET, the callback parameters will be delivered as a query string.

Move SIMs between Subaccounts

If you are using Subaccounts, you can transfer new SIMs between your accounts.

While using the master account's credentials, use the AccountSid parameter to provide the Account SID of the account you wish to own that SIM. SIMs can be moved between accounts the following ways:

From the master account to a subaccount.
From a subaccount to the master account.
From a subaccount to another subaccount.

If the SIM you are moving is assigned to a Rate Plan, you must also pass the SID or unique name of a Rate Plan that belongs to the new account, or null, in the RatePlan parameter of your Update request.

Reset a SIM's connectivity

You can force your SIM to detach from the cellular network and reconnect by updating the Sim resource's ResetStatus to resetting.

Once the reset request is accepted by our downstream provider, the ResetStatus will return to null. You cannot issue another reset request while the ResetStatus is resetting.

View SIM lifecycle events

A SIM's lifecycle events are audited and reported by Monitor Events. An update to a Sim resource results in a Monitor Event with an Event Type of wireless-sim.updated.

The valid resource_properties that can be reported are rate_plan_sid and status. For each, a previous and updated value may be provided. For example:

"event_data": {
  "resource_properties": {
    "rate_plan_sid": {
      "previous": "WP0195dea2f0b1e00dbc54d0715e36e2db",
